Ion Series

Microbalances | Semi-Microbalances | Analytical Balances

Weighing is at the heart of many laboratory processes and the Ion Series offers the features, performance and standard accessories to bring real convenience to your lab. With the six balances of the Ion Series, you can choose a capacity as high as 520g or a microbalance with readability down to 1μg. The BM-20 and BM-22 let you handle with confidence even trade quantities of valuable or degradable substances.

Critical to precision weighing is static control, which is why the direct current fanless ionizer is standard on all models.

The automatic response adjustment function uses environmental data from built-in sensors to compensate the balance’s characteristics to deliver fast and stable results. Calibration is also automatic and always available with a single key press. A range of accessories add extra convenience.

Microgram (μg) Measurements Made Simpler. The BM-20 and BM-22 microbalances have the performance and standard accessories to simplify microgram measurements. The Ion Series now makes microgram (μg) measurements accessible to all researchers and offers a real choice in microbalances.

Eliminating Frustrations in Precision Weighing

top

 

Error Diagram

The Challange

Static, while often overlooked, can seriously degrade precision weighing. An electrostatically charged object induces the opposite charge in nearby objects. The resulting attraction causes inaccuracies as shown below.

Filter papers, disposable weigh boats and plastic centrifuge containers can all become charged just from normal handling. And charged powders can be displaced, causing cross-contamination.


The Solution

Better, Safer Measurements.
Understanding and removing static electricity is critical to accurate weighing. The built-in ionizer improves weighing by eliminating static. And because the direct current (DC) method is used, the ionizer needs no fan. So, you can neutralize static in fine powders without the risk of compromising your sample.

Static control is so important the built-in ionizer is standard in all Ion Series balances. Simply hold the sample in the upper neutralizing chamber for a few seconds before weighing.

 

Standard Accessories

Interlocking Doors


Interlocking Doors
Use this feature to open either door from the opposite side, or open both doors with one hand. You work more quickly and efficiently when you can use both hands.

 

Ports


Ports
All BM Series balances come with the AD-1688 Data Logger, A&D WIN-CT software, and are compliant with GLP/GMP/GCP/ISO industry best practices.

RS-232 and USB ports are standard on all BM Series balances.

 

Weighing Data Logger


AD-1688 Weighing Data Logger
Stores up to 5,000 weighing results with date, time, temperature, humidity and atmospheric pressure. Download to a PC via USB port.

 

Weighing Pans


Dedicated Weighing Pans for BM-20/22
